Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
2. The method according to claim 1, wherein the group DCI has a bit size that is an integer multiple of the number of bit blocks N in the group DCI.
This invention relates to wireless communication systems, specifically to the design of downlink control information (DCI) groups for efficient transmission. The problem addressed is optimizing the bit size of DCI groups to improve transmission efficiency and reduce overhead in wireless networks. In wireless communication, DCI carries critical control information for user equipment (UE), and grouping DCI messages can enhance spectral efficiency. However, improper bit sizing can lead to wasted resources or transmission errors. The invention describes a method where a group of DCI messages is structured such that the total bit size of the group is an integer multiple of the number of bit blocks within the group. Each bit block represents a segment of the DCI group, and ensuring the total bit size is an integer multiple of the block count simplifies encoding, decoding, and resource allocation. This approach prevents partial bit blocks, which could complicate processing and introduce inefficiencies. The method ensures that the DCI group can be evenly divided into complete bit blocks, allowing for more predictable and efficient transmission scheduling. This optimization is particularly useful in high-density wireless networks where control channel resources are limited. By aligning the bit size with the block count, the system reduces overhead and improves reliability in DCI transmission.

This invention relates to wireless communication systems, specifically to methods for managing Hybrid Automatic Repeat Request (HARQ) processes in downlink control signaling. The problem addressed is the efficient transmission of HARQ feedback information for multiple user equipment (UE) devices, particularly in scenarios where multiple HARQ processes are active for a single user. Traditional methods may lack flexibility in handling varying numbers of HARQ processes per user, leading to inefficiencies in control signaling. The invention describes a method for structuring downlink control information (DCI) to include bit blocks, where each bit block contains M bit fields. Each bit field corresponds to a HARQ-identifier (HARQ-ID) for a single user, allowing the system to track and manage multiple HARQ processes per user. The value of M, representing the number of HARQ-IDs per user, is either predefined or semi-statically configured, providing flexibility in adapting to different network conditions or user requirements. This approach ensures that the control signaling can dynamically accommodate varying numbers of HARQ processes without excessive overhead, improving efficiency in downlink control channel transmissions. The method supports both fixed and configurable configurations of M, allowing for optimization based on system design or operational needs.
4. The method according to claim 3, wherein a value of M of different users is configured to be the same or different.

The method involves assigning a value to M for each user, where the value can be either uniform across all users or individually tailored. This flexibility allows the system to adapt to different user requirements or operational constraints. The method may be part of a broader system that involves user authentication, resource allocation, or data processing, where the value of M influences how the system behaves for each user. By allowing M to be configurable, the system can balance between consistency and personalization, improving efficiency or user satisfaction. The invention is particularly useful in applications where user-specific adjustments are necessary, such as in access control, data management, or service provisioning. The method ensures that the system can operate with either uniform or diverse settings for M, depending on the use case.
7. The method according to claim 1, wherein in the case that the number of invalid bit blocks is greater than 1, a plurality of invalid bit blocks are set to have the same value.
A method for managing invalid bit blocks in a data storage system addresses the problem of efficiently handling multiple invalid bit blocks to improve data integrity and storage efficiency. The method involves detecting invalid bit blocks within a storage medium, where an invalid bit block is a block of data that is corrupted, unreadable, or otherwise unusable. When more than one invalid bit block is identified, the method sets all invalid bit blocks to the same value, ensuring consistency and simplifying error handling. This approach prevents misinterpretation of corrupted data and reduces the complexity of error recovery processes. The method may be applied in various storage systems, including solid-state drives, memory devices, or other non-volatile storage media, where maintaining data reliability is critical. By standardizing the value of invalid bit blocks, the system can more effectively manage errors, improve data recovery, and enhance overall storage performance. The method may also include additional steps such as identifying the invalid bit blocks, determining their locations, and applying the standardized value to ensure uniformity across the storage medium. This technique is particularly useful in environments where data integrity is paramount, such as in enterprise storage systems or critical data applications.
8. The method according to claim 1, wherein the maximum numbers of HARQ processes supported by different users within a single said group DCI are the same, wherein the number of bits occupied by the HARQ-ID is determined by the maximum number of HARQ processes.
In wireless communication systems, particularly in 5G and beyond, efficient downlink control information (DCI) transmission is critical for managing hybrid automatic repeat request (HARQ) processes. A challenge arises when multiple users share a single DCI message, as the HARQ process identifiers (HARQ-IDs) must be clearly assigned to avoid miscommunication. This invention addresses the issue by standardizing the HARQ process allocation within a group DCI to ensure consistent and predictable resource utilization. The method involves grouping users such that all users within a group share the same maximum number of HARQ processes. This uniformity simplifies DCI design by fixing the number of bits required for the HARQ-ID field, which is directly derived from the maximum HARQ processes supported by any user in the group. By aligning the HARQ process limits across users, the system avoids inefficiencies caused by variable bit allocations, reducing overhead and improving reliability. The approach ensures that the HARQ-ID field size is optimized for the group's highest requirement, preventing unnecessary bit expansion while maintaining clarity in process identification. This method enhances DCI efficiency in multi-user scenarios, particularly in dense network deployments where control channel resources are constrained.
9. The method according to claim 8, wherein the indication information carried in each bit block of the group DCI indicates an Acknowledgement (ACK) message of the HARQ process corresponding to the indication information.
The invention relates to wireless communication systems, specifically to methods for transmitting and receiving downlink control information (DCI) in a group-based manner to improve efficiency and reliability. The problem addressed is the need for efficient feedback mechanisms in high-speed wireless networks, particularly for hybrid automatic repeat request (HARQ) processes, where timely and accurate acknowledgment (ACK) messages are critical for maintaining data integrity and throughput. The method involves grouping multiple HARQ processes and transmitting DCI that includes indication information for each process in the group. Each bit block within the DCI carries an ACK message corresponding to the specific HARQ process it indicates. This allows the receiving device to quickly determine the success or failure of data transmission for each process in the group, reducing latency and overhead compared to individual feedback transmissions. The DCI may also include additional control information, such as resource allocation or modulation and coding scheme (MCS) details, to further optimize communication efficiency. By grouping HARQ processes and embedding ACK messages within the DCI, the method enhances the reliability of feedback mechanisms while minimizing signaling overhead. This is particularly useful in scenarios with high data traffic or limited bandwidth, where efficient feedback is essential for maintaining performance. The approach ensures that ACK messages are transmitted in a structured and synchronized manner, improving overall system efficiency.
